MatrixTransformationGeometric Construction
This example demonstrates how to dilate a line using similarity transformation. Key mathematical concepts include similarity transformation, geometric transformation, and proportionality. Using GeoGebra commands Line, Point, and Dilate, a line and its dilated version can be constructed. Suitable for students at the junior high school level and above to learn about geometric transformations and similarity.

GeoGebra Commands & Parameters

  1. Line(A, B) → a
  2. Point(xAxis) → C
  3. Dilate(a, 0.5, C) → a'
  4. Point(a') → A'
  5. Point(a') → B'

AI Drawing Prompt Reference

Draw a line AB, then take a point C on the x-axis as the center point, and perform a similarity transformation with a scale factor of 0.5 on line AB with C as the center to get line A'B'.
The prompt above was compiled from the original drawing commands and is for reference only.
